SEPARATOR FOR COTTON-SEED-OIL. MILLS.

SPECIFICATION forming part of Letters Patent No. 366,540, dated July 12,1887.

Application filed August 20, IFEG. Serial No. 211. 120. (No model.)

Little Rock, in the county of Pulaski and State of Arkansas, haveinvented certain new and useful Improvements in Separators for Cotton-Seed-Oil Mills; and I do declare the following to be afull, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 of the drawings is an end elevation, partly in section andpartly broken away, of my improved separator, &c. Fig. 2 is a side viewof the same, partly broken away to better show the operating parts. Fig.3 is an enlarged face view of one of the heaters, and Fig. 4 is a sideview of the same.

My invention relates to separators designed for use in cottonseed-oilmills and other places for the purpose of separating cottonseed mealfromthe cotton-seed meal; and the invention consists in the constructionand novel eombination of parts, as hereinafter described, and pointedout in the claim.

Referring by letter to the accompanying drawings, A designates therectangular case or box in which the beaters, screen, brushes, andconveyer are placed, said box being provided on its top, near its frontend, with a feed-hopper, B, at the discharge end of the screen 0, with adischarge-chute, D, through which'the hulls of the cotton-seed aredischarged, and at the discharge end of the con veyer withmeal-discharge chutes E F, through which the cotton-seed meal isdischarged into any suitable receptacle. I may use only one conveyor, G,or I may use two conveyors, arranged side by side, and instead oflocating the mealdischarge chute or chutes at the end of the conveyor Imay locateit or them intermediate of the ends of said conveyer, if Isoelect.

H designates the beater-shaft, which is mounted in hearings in the endsof the box or case, and is provided at one end with a driving-pulley, I,by means of which power is imparted to drive the shaft. Near thedrivingpulley I the beater-shaft H is provided with a sprocket=wheel, J,which is connected by a sprocket-chain, K, with a sprocket-wheel, L, onthe conveyer-shaft M. The beater-shaft H is provided withradially-extending beaters N, the threaded ends of which are screwedinto seats in the beater-shaft,.said seats being arranged spirallyaround the beater-shaft. The outer ends of the beaters are flattenedinto paddle or fan shape. The heaters are arranged with their bladesalternately at right angles to the axis of the rotating beatershaft andparallel with said axis.

0 indicates a concave metallic screen, which is arranged in the beaterframe or case concentric with and below the beater-shaft. Thelongitudinal edges of this screen are secured to the side walls of thecase to sustain the same in position.

' Below the concave screen (J, at opposite sides thereof, and arrangedto slide in bearings in the frame of the box or bin, are thebrush-supporting rods P I, having the corresponding ends of thelongitudinal series of brushes Q Q R on each side secured to them, sothat the said rods and brushes reciprocate together. The brushes arepreferably equidistant, and are made on the arcs of similar circlesconcentric with the beater-shaft H, and when reciprocating with the rods1? move longitudinally upon the lower surface of the screen 0 andprevent the meshes thereof from being clogged by the material. It isobvious that these brushes, or their frames, which are placed on thesupportingrods P P, may be secured thereto by set-screws or other commonfastening devices.

One of the brushes (designated by R) is connected through its dependingarm S to the in her end of a pitman-rod, T, the outer end of saidpitman-rod T being connected to a crank consisting of the disk t andwrist'pin t at the upper end of a vertical shaft, J supported insuitable bearings at the front end of the box or case, and provided witha miter-gear, V which engages a miter'gear, \V, on the end of theconveyor-shaft and operates the brushsupporting rods and brushes.

The pitman-rod may be operated by hand, if desired, in which event themiter-gearing and crank-shaft may be disconnected, or omit ted entirely,if desired.

The ground cotton-seed is introduced at the feed-hopper, and the heatersact as conveyers and also as fans, and convey the meal and hulls in thedirection toward the rear end of the shaft over the perforated bottom.Every alternate beater acts as a fan, so that wet or damp hulls arecleaned, as the fans cool and dry the coagulated meal that adheres tothe Having described this invention, what I claim, and desire to secureby Letters Patent, is'

combination, with the longitudinal screen made transversely on the areof a circle, the shaft concentric with said screen, and the heaterssecured to the shaft in spiral 1ines,'of

the single series of equidistant curved brushes concentric with andresting against the under surface of the screen, the reciprocating siderods having the ends of the brushes secured to them, and mechanism,substantially as described, whereby the brushes and rods arereciprocated, substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.
